The 'Girl On The Train' star - who has Hazel, two, and Violet, three months, with her husband John Krasinski - insists she is a lot more chilled out this time around when it comes to motherhood.

She said: "I wonder if it's the second kid - you're so relaxed, and then they're relaxed. Your energy is not like, 'Oh my God, am I gonna kill this child by something that I'm doing?'"

And the 33-year-old actress also gushed about how well Hazel has taken to being an older sibling.

She told Extra TV: "She's taken to it well. She's doing brilliantly, she's very kind to her ... She was sort of indifferent, and then really loved her."

Meanwhile, Emily previously opened up about "mummy cults", admitting they put unnecessary pressure on women.

She said: "There is a huge societal pressure on women when it comes to motherhood, and these 'mummy cults' that go on. It makes women feel that they have to be a bit defensive about the choices they make - whether they want to be a mother or whether they don't, whether they want to breastfeed or whether they don't. I could go on and on.

"In the domestic world, I think it's when women can be a bit cruel about each other, more so than any other environment. And I think this film really captures that ... I think women will really relate to the film and see aspects of themselves, or themselves fully, in any one of these characters."
